Study on the most Reasonable Layers of Reinforcement for Stone Arch Bridge through Section Enlargement Method

Abstract

In order to research the most reasonable layers of reinforcement for stone arch bridge through section enlargement method, based on a bridge, on the premise of ensuring coordinated consolidation layer and original structural deformation, the finite element software is adopted to analyze the stress state of old and new concrete with different thickness of reinforcement for arch ring with the detailed exploration and structure evaluation data. Through consolidate the optimal reinforcement layer, in order to maximize the whole bridge bearing capability, then each section mechanical performance is improved, achieving ideal reinforcement, the conclusion can be used to reference for similar reinforcement design and construction, reducing workload of trial and calculation to increase the cross section technology.
